Problem 3. Consider a non-inverting-Schmitt trigger with reference voltage as shown in the figure. High and low voltage levels are Vh = 10V and V? =-10V. Also, Ri=1k. a) Find R2 and VREF for having a hysteresis width of 2 V and a switching voltage of Vs = -3V. Also find the high and low crossover (threshold) voltages (Vth and VtL). (8 points) b) Sketch the voltage transfer characteristics (hysteresis graph) with voltage values clearly identified. (3 points) (11 points) R | R2 VREFO w vo Vio + R1 R2
